I used TI-83 and think it's easier to use than TI-86. In general I think TI-83 is good (although, I've only gone up to Calc AB and at beginning of Discrete Math).

TI-89, I've used before, although not as main calculator (couldn't be bothered to learn it), and it is indeed very powerful, if your class allows you to use it then by all means buy it since I think it is a major upgrade from 83.

Heh.. good ol' Waterloo's Maple.. fantastic program.

I vote TI-86. I've had a TI-86 and a TI-92 for 8 years and the TI-92 rarely ever gets used. Probably the only convenient thing about the TI-92/89 is its ability to do indefinite integrals and integrate or differentiate using variables. For the most part though, if you're going to learn calculus, do not rely on using something like a 89 to do the work for you because then you never learn anything.

I really REALLY recommend the HP-48/49 over any TI.
It takes a little bit to get used to RPN, but once you do, its SO much easier. Particularly when youre dealing with many numbers/operations.
Even if you have to go over your $50 budget, its well worth it.

I cant even use a regular calculator anymore. I even have an HP48GX emulator for my computer.

see for me, its up to the professor. My Multivariable Calc, and Diff Equ professors didnt allow the use of calculators. I wholeheartedly disagree wiht this policy, I mean after all we have the technology available to us, why can't we use it? But alas, they hand out the grades, so I submit to their authority!

P.S. I have both a TI-84plus silver edition and a TI-89.

I would suggest the Ti-89 as well. It has all the features that you need and it wont look like an old computer like the Ti-92. This way you might slip away with having it into exams that you are not supposed to carry it.

On your budget your best bang for the buck calculator is going to be the Casio FX-9750G plus which can be found new for $35-50 at many of the office stores. I use a 9850GB-plus I bought on ebay for $30 shipped and love it. Less than half the price of the TI calcs with about 95% of the capabilities. It easily got me through four seperate calc courses as well as physics, strength of materials, and thermodynamics. The only true downside is that so many college math texts build their calc exercises on the TI calculators but a little trial and error and you'll find the same things on your Casio. After a while you'll become just as handy with it as anyone with the TI
